This paper investigates the compressive, tensile, and flexural behavior of concrete produced using waste tire rubber in the form of fibers, and also estimates its capacities with artificial neural networks (ANN). This study aims to reuse waste tires in concrete production by considering environmental awareness and recycling, both of which are becoming increasingly important. Three different ratios of fiber-formed waste tire rubber, specifically 5%, 10%, and 15% by volume, were utilized. Slump value measurement, compressive strength, splitting tensile strength, and flexural tests were performed on the samples. The distribution of rubber fibers in the concrete was investigated by SEM. Thanks to the developed algorithm, ANN was performed, and the optimum design configuration was determined. When the results of the analysis were examined, it was observed that the use of waste rubber in the form of fiber increased the workability of the concrete, while it caused a decrease in the compressive strength, cylinder splitting strength, and beam bending tensile strength . As the ratio of tires used increases, the more the reduction in these strengths becomes pronounced.
